Definitions

  • T his invention relates to artificial filaments, yarns, or threads, and to their production by the extrusion of spinning solutions through jets, nozzles, or other spinning orifices.
  • filaments or threads of artificial silk or the like are given a regular or systematic irregularity in denler by drawing them at varying linear speeds in the course of their production so as to stretch them at any desired intervals.
  • the varying stretch imparted to the filaments or threads results in a correspondingly varying denler, the variations occurring at any desired intervals and to any desired degree, while extending any desired amount along the length of the filaments or threads (hereafter referred to as filaments).
  • the filaments may be caused to pass to a roller of circular cross-section whose speed, which may normally be the same or greater than the speed of extrusion of the filaments, is varied at intervals and to amounts and for periods corresponding to the frequency and degree and length of the predetermined irregularity required to be imparted to the filaments.
  • the filaments may be caused to pass round a roller or the like so mounted and/or of such cross-section as to vary the linearspeed of the filaments.
  • rollers of elliptical or other non-circular cross-section may be employed, or rollers of circular or other cross-section may be eccentrically mounted.
  • rollers may be arranged to rotate at a constant speed, or by varying their speed of rotation, further irregularities may be imparted to the filaments over and above those impart-ed owing to the form or mounting of the roller.
  • a roller of irregular cross-section for use according to the invention may be constituted by a pair of flanges each having a number of radial or other slots adapted to receive bars which extend between the flanges, ad-
  • a roller having any of the forms described above, and rotating with either constant or varying peripheral speeds, may be caused to move bodily e. g. to and fro, while rotating, either continuously or intermittently, the movement causing the filaments to be stretched irregularly and thus to 1receive a reduced denier at desired interva s.
  • a still further method of carrying out the invention consists in leading the filaments over or round a rotating roller or drum whose diameter varies along its length, the filaments being engaged at successive parts of their length by parts of the roller or drum of different diameters.
  • the linear speed imparted to the filaments varies in accordance with the diameter of the drawing roller or drum, the length of the filaments between the spinning orifices and the roller or drum is stretched to varying" extents, with the production of corresponding variations in denier.
  • the filaments may be caused to be engaged by the different diameters by traversing the filaments along the roller or drum or by traversing the drum itself, as by moving a guide for the filaments or mounting the drum on an axially slidable shaft. Any predetermined frequency of variation may be obtained by adjusting the rate of traverse of the filaments relative to the roller or drum, and, of course, by varying the length of the traverse, the effect of the roller or drum on the filaments may be modified.
  • the roller or drum may have any suitable form, depending on the nature of the variations to be produced, for instance, it may be arranged as a truncated cone by means of which a maximum variation in denier may be obtained corresponding to the difference between the diameters of the two ends of the cone.
  • the roller or drum may, moreover, have a non-circular cross-section and be driven at varying speeds.
  • the filaments may be wound, or twisted and wound, after passing round the stretching roller or the like, or they may be collected on the roller or the like itself.
  • a further method consists in drawing the filaments at varying linear speeds by eriodically lengthening the path followed y the filaments to a winding or twisting and winding device, the lengthening being efi'ected by one or more bars or rollers (driven or idle) which are moved across the path of the filaments at a frequency and to an extent adjusted in accordance with the variations in denier to be imparted.
  • the filaments may pass over and under a pair of bars or rollers arranged for oscillation across the direction of feed of the filaments.
  • any suitable means may be employed for controlling the speed of operation of the stretching devices, and the devices may be arranged to give a gradual or more or less abrupt change from one denier to another, as desired.
  • the driving of the devices may be by means of electric motors whose speed is controlled in accordance with the variations in denier required. Further,elliptical or other irregular gears may be employed for driving the elements of the stretching devices.
  • the variations in denier produced according to the invention may appear at' regular short or regular long intervals of length or at regularly varying intervals, and variations of different degree or extent, or both, may appear at any desired intervals.
  • one or more groups of irregularities may appear in regular sequence or in any desired order or at any desired intervals.
  • one or more short variations may alternate with one or more longer variations, or groups of short and long variations may alternate with short or long variations or with other groups of short and long variations, always with the object of producing a regular or systematic effect from the alternating or periodically recurring irregularities of denier of the filaments, yarns,orthreads.
  • Orperiodiealirregularities forming groups of, for example, 2, 3, 4, 6 or 10 or more variations may occur on the filaments, yarns, or threads, the groups alternating with each other or appearing in any desired order according to the effect to be produced.
  • the yarns or threads which have received the regular irregularities as above described may be wound or twisted and wound for example, by means of cap-spinning devlces, or centrifugal boxes.
  • the filaments of varying denier may be formed into yarns, either alone or twisted or doubled with threads of other natural or artificial filaments or fibres. Or they may be cut or reduced to staple lengths, either continuously with their production or subsequently thereto, and spun into yarns, either alone or mixed or blended with other natural or artificial filaments or fibres, and such spun yarns may, if desired, be twisted or doubled with the same or other yarns to form any desired type of thread.
  • Yarns or threads with irregular denier according to the invention impart a novel effect to fabrics or articles wholly or partly formed from them, by reason of the differential effect produced by the variations, and this efi'ect may, moreover, be enhanced when the fabrics or articles are dyed, printed, or otherwise coloured, because of the regular irregularity of denier of the yarns or threads causing different penetration of the dyestufi or other colouring matter to be efi'ected, a great variety of colour efi'ects thereby being produced.
  • The, yarns or threads of varying denier may be applied to the production of fabrics or articles, either alone or in association with yarns or threads of regular artificial silk or of other natural or artificial filaments or fibres, and may be utilized to give any desired design or pattern. They may be used, for example, in the warp and /or weft in weaving operations; in knitting operations, for 'example in the production of warp-knitted fabrics; in circular hosiery or other knitting machines; in braiding or cording operations; in net or lace-making operations; or in any other fabric-forming or textile operations.
  • While the invention applies particularly to filaments or threads of varying or irregular denier, produced by the dry or evaporative method, and especially filaments or threads having as a base cellulose acetate or other cellulose derivatives.
  • cellulose formate, propionate, or butyrate such as cellulose formate, propionate, or butyrate, thiocarbamic or alkoxy-alkacyl esters of cellulose, methyl, ethyl or benzyl cellulose, or the condensation products of cellulose and glycols or other polyhydric alcohols
  • it applies likewise to filaments or threads of varying or irregular denier produced by the wet or coagulation method whether having a base of cellulose acetate or other organic derivatives of cellulose, or composed of a reconstituted cellulose. such as viscose, cuprammonium, or nitrocellulose silk.

  • the filaments 5 are shown emerging from a spinning cell 6, the filaments being caused to pass round a roller 7 of elliptical section mounted for rotation on a shaft 8. On leaving the roller 7, the filaments pass to a thread guide 9 and to a capspinning device 10. It will be seen that as the filaments are engaged by the roller 7 in the position shown in full lines, the filaments will be drawn from the .cell 6 at a speed equal to the peripheral speed of the roller at the ends of its major axis, this speed being greater than the speed of extrusion of the filaments.
  • the filaments are drawn from the cell at a speed corresponding to the peripheral speed of the roller at the ends of its minor axis.
  • the filaments are thus stretched to different extents depending on the part of the roller with which they are engaged, the stretch varying from a maximum when the engagement is at the end of the major axis to a minimum at the end of the minor axis.
  • two variations in the amount of stretch, and, therefore, in the denier of the filaments are imparted to the length of filaments drawn from the cell during the revolution.
  • Fig. 2. the filaments 5 on leaving the cell 6 are caused to pass round a roller 11 mounted on a shaft 12 carried by the upper end of an arm 13. the lower end of the arm being pivoted about a shaft 14.
  • Pivoted at 15 on the arm 13 is an eccentric rod 16 driven bv means of an eccentric 17 the arrangement being such that the arm 13 and the roller 11 are caused to oscillate about the shaft 14 to an extent and at a rate dependent on the throw of the eccentric 17 and the speed at which the eccentric is driven.
  • the roller 11 is rotated by means of a pulley 18 connected by a belt 19 to a pulley 20 freely mounted on the shaft 14.
  • the pulley 20 is in turn driven by a belt 21.
  • the roller 11 by its rotation, draws the filaments 5 from the cell 6 and variations in the length thus drawn are effected by the oscillatory motion of the roller.
  • the rate at which the eccentric 17 is driven with respect to the peripheral speed of the roller 11, e. g. by the use of elliptical gears varying amounts of stretch and consequent variations in the denier of the filaments may be effected.
  • variable stretch imparted to the filaments may be confined to a particular length of the filaments being produced, such an arrangement being shown in Fig. 2.
  • a roller 23 is arranged.
  • the filaments are caused to pass round the roller 23 which is driven at a rate equal to or exceeding the rate of extrusion of the filaments, so that the stretch imparted according to the invention is confined to the length of filaments between the roller 23 and the stretching apparatus, the length 24 of the filaments between the jet 22 and the roller 23 being free from such stretching.
  • Fig. 3 illustrates at (a) a stretching roller of roughly square cross-section but having rounded corners, and at b) an approximately triangular section roller.
  • a roller of circular cross-section but mounted eccentrically for rotation is shown at (c) Fig. 3, and at (d) a roller of similar cross-section to (b) is shown also mounted eccentrically.
  • rollers of such cross-section many variations in the amount and frequency of the variation in denier may be imparted.
  • the variations may be produced in groups on the filaments, the recurrence of the groups to form a pattern depending on the form of the roller and the manner in which it is driven or moved. 7
  • Fig. 4 the filaments 5 are shown passing round a conical roller 25 mounted on a shaft 26.
  • a thread guide 27 is carried by a longitudinally movable bar 28, the bar being given a to and fro motion in any suitable way, e. g. by means of a cam, or by a crank disc 29. a pin 30 of which works in a fork 31 carried by the bar 28.
  • the filaments are caused to engage parts of the roller 25 which move at different peripheral speeds, and the consequent variations of stretch imparted to the filaments result in corresponding variations in denier.
  • the roller 25, which may be driven at a varying speed may have an ir-- regular cross-section such as is indicated at (a) and (b) of Fig. 3, or it may be eccentrically mounted as shown at ('0) and (d) of Fig. 3.
  • filaments 33 on withdrawal from the spinning cell 34 are led to a device comprising an arm 35 mounted for oscillation on a shaft 36.
  • Bars 37 project from the arm 35 in a direction parallel to the shaft 36, a bar 37 being arranged on each side of the shaft.
  • An eccentric 38 driven in any suitable manner is connected by an eccentric rod 39 to an arm 40 fixed to the shaft 36.
  • the arm 35 is thus caused to perform an oscillatory motion with an ampliture governed by the throw of the eccentric 38 and the position of the connection 41 between the eccentric rod 39 and the arm 40, a series of holes 42 being provided on the arm 40 to permit of the connection being adjusted.
  • the bars 37 are preferably adjustably mounted on the arm 35, a series of holes 43 being provided on each half of the arm.
  • the filaments 33 pass round. a feed roller 44 and are collected in any suitable manner. It Wlll be seen that as the filaments pass first over one bar 37 and then under the other before reaching the roller 44, the oscillation of the arm 35 causes a variable pull to be imparted to the filaments which are thereby stretched to a varying extent, with the consequence that they receive variations in denier along their length.

  • Slots 48 are formed in each flange, and they are arranged to receive bars 49 which extend from one flange to the other and may be secured in any desired position in the slots 48 by means of nuts 50.
  • the rods constitute a roller-like surface, the periphery of the roller depending on the positions of the rods in the slots.
  • Fig. 8 shows four of the rods arranged to form a square 51, the remaining rods being held out of position near the hub.
  • Fig. 10 shows two diametrically opposed rods mounted in the slots, all the remaining rods being removed.
  • the device may operate as a roller of non-circular periphery which, by reason of the varying peripheral speed of the roller, imparts a variable denier to the filaments passing over the roller to a winding device. Instead, however, of the filaments proceeding to a further winding device, they may be collected on the bars in the form of a hank, and in Fig. 10 a hank 52 is shown in the course of formation on the single pair of rods 49.
  • the irregularity of denier may be caused to appear in a great variety of arrangements on the filaments, varying from a simple alteration in denier occurring at regular intervals of any extent along the length of the filaments to a grouping of alterations in denler occurring at regular or irregular intervals.
